VALVE.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed December 7, 1908. vSerial No. 466,375.

To all fwlzom 'it may concern Be it known that I, OLIVER SCHLEMMER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Valves, of which the following is a specification.

The ob"ect of my invention 1s to provide a valve of'improved construction and operation and my invention consists in the combination and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1, is a sectional ele vation of a valve embodying certain features of my invention; Fig. 2, a perspective view of the valve disk; Fig. 3, a perspective view of the stop for regulating, the opening movement. of the valve, and Fig. 4 a top plan view of the stop.

In the construction shown in the drawing there is a valve casing A recessed in its lower portion to receive the valve seat B and the upper end of the union elbow C. The valve seat slips loosely into its recess resting against shoulders a, on which it is positioned by pins b, and against which it is held by the upper end of union elbow C. A flange o is provided on elbow C which is engaged by the threaded coupling D whereby the elbow may be adjustably held in position and the valve seat also secured in its position. The union elbow C is swiveled coaxially with the valve seat and its valve so that when` adjusted or turned it will always afford a uniform delivery to the valve. By this construction it will be seen that the elbow may be set to any angle to receive a connecting pipe without affecting the action of the valve, and the valve seat may be readily removed or replaced when desired. The valveseat B isprovided with openings or ports b and a valve disk E having corresponding ports e is rotatably mounted thereon by means of a plug e extending through the center of the valve seat. A washer e2 serves to secure the valve disk to the valve seat. On top of the Valve disk, on one side, is provided a projection F having an inclined curved upper surface f and at the other side of the disk there is provided a permanent stop f" adapted to coperate with a projection from the wall of the casing to limit the rotation of the valve at closing posit-ion. At one side, casing A is provided with a boss a adapted to receive threaded packing plug G through which passes a rod H carrying a pin zprojecting through a screw slot in the boss a. The rod H projects into the valve casing to contact with surface f ot' projection F on the valve disk. suitable packing g being provided to prevent leakage. It will be observed that by turning rod Il, the pin 171` traveling in the screw slot will cause the rod to rise or fall causing' its lower end to strike surface f at different points when the valve disk is 4rotated and thus regulate the extent of rotation of' the valve disk, and the extent to which the valve ports are opened. On the upper side of the valve disk is provided a hub c having' a square or rectilinear socket 04 in which the similarly shaped lower end of the valve stem J is loosely inserted. The valve stem J carries a flange or shoulder`j which imprisons a packing disk j against the casing A and around the valve stem. A

spring l( is imprisoned between the flange 7' and the valve disk E and serves to hold the valve disk to its seat and flange j against packing j. A suitable packing L is provided around valve stcm -I on the outside of the casing. By this arrangement it will be seen that the valve disk will be held to its seat and the interior packing compressed around the valve stem to prevent leakage around the valve stem in either direction or permit repacking of the outside packing L at any time.

`WhileI have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of modification without departing from the spirit of the invention. I therefore do not wish to be limited to the exact construction set forth, but

What I claim as new and desire to secure by Letters Patent is:

In a device of the class described, the

combination of a valve casing; a valve seat with said inclined curved surface, and a pin in the casing having a port; a rotatable la on the rod taking into a screw slot, subvalve having a port adapted to register with st'antially as speciiied. the seat port; a permanent stop adapted to OLIVER SCI-ILEMMER.

5 limit the movement of the valve at closing Witnesses position; an inclined curved surface carried by the valve; a rod H adapted `to Contact ARTHUR E. GEORGE, Y BnArToN Gr. Browns. A
